## Data quality

- Reported capacity varies by convention: the project site states nominal 900 MW, an EIA-linked record reports 1,008 MW, and ERCOT records a 932.6-MW rating. The grid-rating figure is used for the directory context. The separately disclosed $105 million January 2023 credit bid was consideration for Brazos Sandy Creek's 25% ownership interest. ERCOT reported Sandy Creek Unit 1 in an extended outage in April 2026. The cited record does not identify a retirement, expansion, or repowering milestone; the outage should not be treated as permanent retirement.
